Observers showing up to a 3 tick (often randomized) delay on 1.14.60.

If observers were working properly, this would not matter. Essentially a 2 tick repeater w/no delay and a three tick repeater.
Even on a 4 tick repeater, The observer randomizes this timing and causes either the rear piston to fire before the circled repeater powers on (thus grabbing the middle piston when extended), or causes the first piston to fire, thus preventing any movement.

The receiver on the left needs at minimum a 2 tick delay in order for the power-off mechanism to work properly.
